python - Processing an uploaded file using Django -

i'm attempting process uploaded csv file using django. main logic of how go doing expressed in both models.py , views.py scripts. once i've uploaded file, i'm unable process of content (in views.py). here 2 scripts, if there's more information can provide, i'd happy to.

in models.py file, have 2 classes, 1 document itself, , other class fields in file.

models.py:

from django.db import models  import os  class document(models.model):     docfile = models.filefield(upload_to='documents')  class documententry(models.model):     document = models.foreignkey(document, on_delete=models.cascade)     field = models.charfield(max_length=250, default="test") 

next, in views.py file uploaded via request.files['docfile'] , pass handle_files() function. however, when try loop through reader, i'm unable access of elements in file uploaded.

views.py:

from django.shortcuts import render django.conf import settings django.http import httpresponseredirect django.core.urlresolvers import reverse  import csv  .models import document, documententry .forms import uploadfileform   def process_file(request):     # handle file upload     if request.method == 'post':         form = uploadfileform(request.post, request.files)         if form.is_valid():              handle_files(request.files['docfile'])              # redirect document list after post             return httpresponseredirect(reverse('process_files'))     else:         form = uploadfileform()  # empty, unbound form      # load documents list page     documents = document.objects.all()      # render list page documents , form     return render(         request,         'upload/process_files.html',         {'documents': documents, 'form': form}     )   def handle_files(csv_file):      newdoc = document(docfile=csv_file)     newdoc.save()      reader = csv.dictreader(open(csv_file))     row in reader:         field = row['field']         entry = documententry(document=newdoc, field=field)         entry.save() 

updated

here full example of handler function:

def handle_files(csv_file):     newdoc = document(docfile=csv_file)    newdoc.save()     open(newdoc.docfile.name) f:       reader = csv.dictreader(f)       row in reader:          field = row['field']          entry = documententry(document=newdoc, field=field)          entry.save()
